## Description

The Adafruit bq25185 is an all-in-one charging and power supply board that supports USB, DC, and solar charging with an integrated 3.3V buck converter. It is an excellent upgrade from MCP73833 or MCP73831-based chargers, combining power path management and regulated output in a single board. Connect a 500 mAh or larger LiPo battery to the JST PH 2-pin port, charge via USB-C or DC/solar input, and power your 3.3V project directly from the regulated output. Smart power path management prioritises external power, sending excess current to the battery instead of constantly cycling it. Key Features USB Type-C Input – 5V at up to 1A with 5.1k CC resistors for universal compatibility; data lines broken out on the bottom DC/Solar Input – 5–18V via side pads with near-MPPT solar optimisation Adjustable Charge Rate – Defaults to 1A, adjustable to 500 mA via onboard jumper Smart Power Path – Prioritises external power, extends battery life by avoiding charge cycling 3.3V Regulated Output – TPS62569 buck converter delivering stable 3.3V at up to 1A 4.5V Max Load Output – Ranges from 3.0V (low battery) to 4.5V (external power active) at up to 1A Status LEDs Orange – Charging Red – Fault Green – 3.3V output active Additional Features Enable Pad – Disable the 3.3V buck converter when not needed Battery Monitoring Pads – Check battery voltage via breakout pads on the bottom Mounting Holes – For easy installation in enclosures Tip: For solar-powered projects, use a 5–7V solar panel. Higher voltage panels will only generate excess heat. Connect via the DC input side pads. Ideal For Portable 3.3V battery-powered projects Solar-powered IoT devices Projects requiring USB + solar charging flexibility Replacing MCP73833/MCP73831 charger setups with integrated power regulation Note: Both outputs may drop to 3.0V when the battery is nearly empty. Use a 500 mAh or larger LiPo battery for best results. Battery not included. Package Contents 1× Adafruit bq25185 USB/DC/Solar Charger with 3.3V Buck Board
